THIS IS A DEVELOPING STORY. This afternoon, Hasbro uploaded the third sneak peek to their YouTube channel. I couldn't really find a main purpose to this sneak peek other than establishing more character development to Sunset Shimmer.
Personally, I like the part with Flash Sentry walking into the scene asking for Twilight. It's like M.A. Larson wants to force FlashLight into existence (I could hope...).
Just your average person who posts about anything pony related and sometimes things about magical blue boxes.
